Answer:
iron
Explanation:
Increasing the number of coils of wire wrapped around the nail increases the strength of the electromagnet, as measured by the number of paper clips the magnet can pick up
Answer:
third charge must be placed at x = -298.11 cm
Explanation:
When two opposite charges are placed in a straight line then the electric field is always zero at a point near to the charge of lesser magnitude
so here let say the point where electric field is zero lie on the left side of 7.00 micro C charge at a distance "x" from it
so we will have net electric field due to both charges will be zero at that point
so electric field of charge 1 must be equal to the electric field of charge 2

so we have

now square root both sides




so third charge must be placed at x = -298.11 cm
